Abstract:Ian R Carstairs reports on efforts to extend the search for extraterrestrial intelligence to X and γ-ray regions. Abstract
Traditional Search for Extra-Terrestrial Intelligence (SETI) strategies have used radio, microwave and, to a limited extent, optical searches. But this ignores the higher energy X and γ-ray regions that a technologically advanced extraterrestrial civilization might use to attract our attention – using messages encoded in discrete photon-counting exchange, much like the signals seen from pulsars. Here, the methods used in high-energy pulsar detection and analysis are reviewed and applied to this new SETI initiative.
